A fourth case of measles has been confirmed in Ireland, the Health Service Executive has said.
The HSE public health teams are managing the issue.
Further details are expected from the HSE.
The number of confirmed cases this year now compares with the total seen in 2023.
The HSE said that due to the ongoing outbreaks in the UK and across Europe, there is a heightened awareness of measles among clinicians in Ireland.
It is finalising plans for the broader rollout of a proactive MMR vaccine catch-up programme in response to a rise in measles cases in the UK and Europe.
The HSE said it is important to note that it already offers MMR vaccine to protect against measles to all children as part of its childhood immunisation schedule for those aged 12 months and four to five years old in Junior Infants.
There is also a free catch-up MMR option via participating GPs for those who may have missed their vaccination when younger.
